Ive got this great plastic container, about 1.5 gallons. Granted, its not the ideal size for a betta, but i figured since the local petsmart has bettas that are about to die anyway, something is better than nothing. its not extremely deep, and im not a big fan of my sideways heater in my current tank.
the question i wanted to ask was if anyone knows of any heaters that aren't too long, but are adjustable.
Its bigger,1.5 gallons, but its like a sandwich container, a heater wouldnt melt the plastic right?
